Yes, we provide a newly designed accessory, for free for Kickstarter backers, to allow you to mount prescription lenses. We provide the frame for the prescription lenses, you optician will have to mount your own lenses in our add-on, which will fit into the SG05.
If you’re wondering why you need an add-on to mount prescription lenses, the simple answer is that most fashion / tech glasses have a lens shape that
do not allow for prescription lenses (Curvature of the lens). With the SG05 we provide, free of charge, an accessory that allows you to mount specific prescription lenses.
Only certified opticians are allowed to mount prescription lenses,

The answer is yes! We will have an online store that will offer all the Lenses and Accessories, such as the Prescription Add-On. we estimate to go live with the store after the campaign is over and around July 2015

The SG04 Speakglass is a product that dates back a few years and it was our first approach to Bone Conduction Technology. SG04 was a pioneer at the time and was radically different compared to the much more advanced SG05. SG04 DID NOT have BCT speakers, it used a wired earbud to be able to listen and BCT was used as a MIC (Usually the wired earbud is NOT shown in pictures by resellers on Ebay, etc.). The SG05 works with NO WIRES as it uses 2 BCT Speakers + an outstanding noise and wind reduction microphone placed in the nose bridge (Our original design). The 2 BCT speakers are also covered by a Buhel patent which is not licenses to anyone or any brand. It's virtually impossible to compare the old SG04 and the upcoming SG05, as they have almost nothing in common. The SG05 is a radically new and improved product while the SG04 was a revolutionary product when it came out a few years ago, but it can be considered outdated in the year 2015. SG05 is the iPhone 6, while SG04 is an iPhone 4 at best, by today's standards.

We added, just for Kickstarter backers, a pair of smoked polarized lenses in addition to the standard three that come with the SG05 PREMIUM Package (7 Total with the TACTICAL Package). The added polarized lenses will be free of charge during the campaign and the addition will NOT delay the production timeline.

Bone Conduction bypasses the ear and transmits directly to the nerves, much like it happens with mammals, such as dolphin and whales. To simplify, it takes over some of the functions performed by the ear and in some cases, depending on the nature of the hearing loss, it can help quite a bit. No parts of the SG05 Bone Conduction mechanism is in direct contact with the ear. This said, benefits for people with hearing loss can vary from case to case, but at times they can be extraordinary. We tested them with a couple of friends and both had different results, but they all had a degree of gain. As I said, I am sure they will not have the same benefits for everyone (Example damaged nerves), but there's a good chance that in less radical situations they will provide various degrees of gain.

We have a patented version of BCT, which basically floats the Noker and drastically reduces leaks. We are the only ones using our patent and we don't plan to license it.
We normally cannot hear leaks when testing the SG05 in a silent room, let alone in an open space. At full volume, you might hear some sort of a sound, but you cannot really put together a conversation and compared to, let’s say, an iPhone, where it's really easy to perfectly hear someone's conversation, the SG05's BCT immensely more private.

One size fits all, the SG05 are really flexible, but sturdy and the nose bridge, which houses the microphone, is very flexible and self-adaptable. As a result your SG05 should not wiggle on your face. We posted some photos of a woman with a thin face and not only they look good, but they fit perfectly. Over thefts few month and before defining the final shape / size, we did endless testing in order to achieve what we think is the perfect measure.
